Two numbers and your fit taste, read off a real size chart. Free, no account. Try it on your photo after.
This is the fitting room your shoppers get: a size read off a real brand’s chart, then the piece on your own photo.
Try CHECK
Two questions every shopper asks. CHECK answers both.
Is this my size? Does it look right on me? On your product page they sit behind one button. Here you can try each on its own. These are the live pieces, not screenshots, running on the same engine your shoppers would use.
“Is this my size?”
An S here isn’t an S there, so nothing is guessed from the letter you wear elsewhere. This reads a real brand’s chart in centimetres, and the letter is just the answer.
The size answer, from two numbers and a fit preference, read off a real size chart.
“Does it look right on me?”

The try-on. The piece on a model, or on your own photo.
How it works
Simple for shoppers. Simpler to install.
For your shoppers
01
Choose a piece
On a product page with CHECK, the shopper taps the fitting-room button.
02
Add a photo
One clear photo, plus height and weight for the size. No account, nothing to download.
03
See it, and the size
The piece on them, and where your size chart supports it, the size to order in your labels.
For you
No code, no developer, no onboarding call.
01
Install from the Shopify App Store
Approve the plan in Shopify. Charges run through your Shopify invoice, so there's nothing else to sign.
02
Add the CHECK block to your product page
In the theme editor: Add block, Apps, CHECK. It's a theme app block, so no code and no developer.
03
Choose where it appears
Pick the products and where the button sits. CHECK works from your Shopify products and their images.
Why CHECK
Built for fashion, not bolted on.
Garment-aware try-on
CHECK reads the piece before it renders it: the type, the length, the construction. The garment on the shopper should be the garment you sell.
The shopper still looks like themselves
Renders are checked against the shopper's own photo. One where the face has drifted isn't shown.
Size and look, together
One fitting room answers both questions: a size from your chart, and the piece on their own photo.
Native on your product page
One button in your product template, in your fonts and colours. It reads as part of your store, not a pop-up.
Usage you control
One plan, one per-try-on rate after it, and a monthly maximum you approve in Shopify.
Failed generations are free
You pay for try-ons your shoppers actually see. A failed, cancelled or blocked render never counts.
Sizing and fit
It knows what a slip dress is.
An S at one brand is an M at the next, so CHECK doesn’t reason in generic S, M, L. It works in centimetres: the shopper’s build against each size on your chart. The letter comes last, in your sizes.
It also reads how the piece is made. A slip dress hangs from the strap, an elastic waist gives a little, a knit sits close, a blazer is about the shoulder. CHECK recognises nine constructions like these and sizes each one against your chart accordingly.
The goal is a better-informed size choice, not a promise. Every answer carries a confidence level, and without a size chart CHECK gives directional fit guidance instead of inventing a size.

A try-on counts when a finished image reaches your shopper. Renders that fail, time out, get cancelled or don’t pass our checks never count, and neither do size recommendations.
No sales call and no setup fee. Install, approve the plan in Shopify, and charges appear on your Shopify invoice.
A month with 300 successful try-ons: $39 + 200 × $0.25 = $89.

Questions
Before you install
What counts as a try-on?
A try-on counts when a finished image reaches your shopper. Failed, cancelled or blocked generations are never billed. Size recommendations are included in the plan and aren't counted as try-ons.
Do I need a developer to install CHECK?
No. Install CHECK from the Shopify App Store, then add the CHECK block to your product template in the theme editor. It's a theme app block, which Online Store 2.0 themes support without code.
Does it work with my product catalogue?
Yes. CHECK works from your Shopify products and their images, and you choose which products show it and where the button sits.
Do I need a size chart?
For a size recommendation, yes: CHECK recommends from your chart, in your size labels. Without one, shoppers still get the try-on and directional fit guidance, and CHECK doesn't invent a size.
Can I limit what I spend?
Paid usage starts only after you set a monthly CHECK limit. Beyond the 100 included try-ons, each successful try-on is $0.25.
What happens to shoppers' photos?
Photos are used only to create the try-on. They aren't permanently stored on our servers, and our processing partners don't retain them. The details are in our privacy policy. Privacy policy.
Which stores is CHECK for?
Shopify fashion and apparel stores, womenswear and menswear: tops, shirts and knitwear, jackets and coats, dresses, trousers and skirts, and full looks.
